Generate F0 contours from Tilt descriptions

Synopsis

tilt_synthesis [input label file] -o [output file] [options]Summary: generate F0 file from tilt or RFC label file [-h ] [-noconn ] [-o ofile] [-otype string] [-event_names string] [-s float]

tilt_synthesis generates a F0 contour, given a label file containing parameterised Tilt or RFC events.

A detailed description of the Tilt intonation model can be found in the Theoretical Overview section.

Options

• -h: Options help
• -noconn: Synthesize events only - no connections in output
• -o: ofile Output F0 file
• -otype: string File type for output label file
• -event_names: string List of labels to be classed as events. Lists are specified as quoted strings with spaces separating each item, e.g.: "a b c d"
• -s: float Frame spacing of generated contour in seconds

Input Intonation Files

The input should be a label file containing the tilt parameters for the events in feature format. An example, in xlabel format, is shown below:

1.79 26     phrase_end ; ev.f0 92.9785 ; position 1.79 ; 

tilt_synthesis can also generate F0 contours from RFC parameters:

intonation_style rfc
#
0.29 26     phrase_start ; ev.f0 115.234 ; position 0.29 ; 
0.53 26     a ; ev.f0 118.171 ; rfc.rise_amp 8.19178 ; rfc.rise_dur 0.12 ; 
               rfc.fall_amp -13.6684 ; rfc.fall_dur 0.14 ; position 0.53 ;
0.77 26     a ; ev.f0 112.694 ; rfc.rise_amp 6.50673 ; rfc.rise_dur 0.1 ;
                rfc.fall_amp -20.5248 ; rfc.fall_dur 0.22 ; position 0.77 ; 
1.53 26     a ; ev.f0 100.83 ; rfc.rise_amp 1.55832 ; rfc.rise_dur 0.11 ; 
                rfc.fall_amp -6.09238 ; rfc.fall_dur 0.11 ; position 1.53 ; 
1.79 26     phrase_end ; ev.f0 92.9785 ; position 1.79 ; 

The feature in the header, "intonation_style tilt" or "intonation_style rfc" is needed for the tilt_synthesis program to know which type of synthesis to perform.
